CNL EPDM Vacuum Suction Cups specifications and compatibility.
Condition :
To deploy several suction pads on uneven workpiece.
Solution :
Selecting multi-bellows type vacuup pads to avoid suction uneven.
Condition :
The screw fitting of small pad size collide the workpiece and has abrasion.
Solution :
Fixing the screw and the vacuum pads with the adhesive. If the screw hole is too small to Inhaling, it can use the solution.
Condition :
How is no failure upon absorbing the cardboard carton or ventilation products?
Solution :
You can use a larger vacuum pad and placed in the center position. If lifting up and has to bear the wind pressure, it should consider to increase the vacuum pads.
Condition :
How does select the vacuum pads when the working area is large?
Solution :
You can use a larger vacuum pad and placed in the center position. If lifting up and has to bear the wind pressure, it should consider to increase the vacuum pads.
Condition :
Must be absorbed from the two sides and to avoid sliding.
Solution :
To improve the absorption strength between the vacuum generator and the vacuum suction cup.
Condition :
In the adsorption of sheet, the pressure is too large and make deformtion.
Solution :
It is recommended to lower the vacuum generator pressure or use a smaller vacuum pads.
Condition :
Vacuum suction cups leave pads marks after using.
Solution :
Wipe the surface of the vacuum cup or reduce the suction of the vacuum generator.
The shape is based on OE ZP type.
NBR, SILICON, EPDM, FKM, ESD NBR/SILICON are acceptable.
Color and hardness can up to your design.

Also named Suction cups, Vaccum cups and vacuum grippers, It use vacuum principle to absorb the workpiece in order to achieve the purpose of moving the workpiece. It used to move the objects or grip the products.
Selecting the type of vacuum pads must consider the operating temperature, stroke, speed, pressure, in order to achieve the most appropriate results.
Electrostatic causes : friction, peel, induction……and etc.
The substance is charged by loss or gain of electrons.
ESD discriminate three levels as below:
SURFACE ELECTRIC RESISTANCE 109~1012
SURFACE ELECTRIC RESISTANCE 106 ~ 109Ω
SURFACE ELECTRIC RESISTANCE 104~106Ω
DIN IEC 1340-4-1 request antistatic material level is 106~109Ω
People walking or friction, is the main source of static electricity. Static electricity build-up can cause electric shock or damage to the precision equipment.
EX : Most moden offices use the central air-conditioning, which use all day will make the air more dry and will cause static electricity easy to produce, gathered and not easy to dissipate.
In the high-precision space, such as wafer production line, operation room, ammunition depot……and etc. The static electricity can not be gathered. It must be discharge via static-conducting agent in order to avoid danger
EX : Doctors need to monitor a variety of index on precision instruments. If the computer and the instrument are interfered due to static and make the reading is not correct. It may lead to a doctor misjudgment and results in irreparable error.
Electro Static dissipative : Suitable for offices, schools, hospitals, public indoor places, factory offices, processing factory.
Conductive : Suitable for surgery room, ammunition depots, IC equipment, wafer production lines, and other precision plant.
SURFACE ELECTRIC RESISTANCE 104~106Ω
SURFACE ELECTRIC RESISTANCE106~109Ω
CNL will use a professional surface resistance measuring instruments to test materials and finished products during the manufacture and QC to sure to meet the above two levels.
These antistatic materials are widely used in vacuum suction cups in order to prevent the production line free from the static electricity and cause product damage.
Electrostatic causes in many ways, such as contact, friction, and so on.
The process can be summarized as: contact → charge → transfer → charge layer formation → charge separation
Equipment or human body cause the electronics up to tens of thousands of volts or even hundreds of thousands of volts, even under normal operating conditions are often caused hundreds to thousands of volts.
The human body due to its own action and contact with other objects - separation, friction or induction and other factors, can bring thousand volts or even tens of thousands of volts of static electricity.
Static electricity is the result of positive and negative charge lose balance.
It is a kind of performance in the object with electric energy. The featuress are high potential, low power, small current and short acting time.
